BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to a positioning device for fitness equipment, and more particularly, to a curved exerciser positioning device.

(b) Description of the Prior Art

Fitness equipment generally available in the market today requires manual operation of the user to cause certain mechanism adapted to the fitness equipment to execute reciprocal movements for achieving the purpose of staying fit and healthy.

To promote the efficacy of exercise, elastic device or any other weight that may increase the load to the user is usually disposed to the fitness equipment. The user after having applied a certain extent of force usually will directly release the elastic device or weight for it to return to its original status by means of return force or central gravity. Therefore, impact is produced upon the fitness equipment by the elastic device or weight in the course of the return, resulting in displacement of the general fitness equipment.

Furthermore, the fitness equipment is generally used indoors. Upon any displacement, the user has to stop exercising and pushing the heavy fitness equipment back into place. How to make the displacement disappear is indeed one of the areas pending further improvements by the manufacturers of fitness equipment.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a positioning device for a curved exerciser to avoid displacement of the exercise in use.

To achieve the purpose, the present invention is essentially comprised of a base, a sleeve extending from the center of the base towards the rear end of the base, multiple through holes in series provided on both sides of the sleeve and both series of through holes correspond to each other to receiver insertion of a pin to penetrate through the sleeve, a buffer extending vertically from the top surface of the sleeve, two swing arms having their first end respectively pivoted to opposite ends of the base with a pedal and a roller respectively provided on the top surface and the bottom of a second end of each of the swing arm, and a rail unit including a shaft with a first end of the shaft inserted into the sleeve of the base and multiple through holes in series laterally disposed that penetrate through the shaft thus to merely secure the shaft in position when the pin penetrates through at the same time those through holes disposed on the sleeve and those disposed on the shaft; the total length of the sleeve and the shaft is adjusted by adjusting relative positions of those through holes respectively from the sleeve and the shaft; an arc platform having the base as the center is each secured to both sides of a second end of the shaft for those rollers from both swing arms to roll thereon.

However, it is to be noted that the description given above is related to general description of certain characteristics of the present invention. To help the examiner and those professionals in reading this specification better understand of the art of the present invention and such art can be executed pursuant to the specification, detailed description of the present invention are given as follows in conjunction with accompanying drawings and preferred embodiments. It is to be further noted that those preferred embodiments given below are only for the explanation of the present invention and in no way to limit the form of the present invention. Therefore, any modification or change to the present invention made within the similar teachings disclosed in the specification shall fall within the range of protection to be granted to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a preferred embodiment of the present invention related to a positioning device for a curved exerciser is essentially comprised of a base 10, two swing arms 20 pivoted to the base 10, and a rail unit 30 to support those both swing arms 20.

A sleeve 11 extends backward from the center of the base 10. Multiple through holes 111 in series are disposed on both sides of the sleeve 11 with both series of through holes 111 correspond to each other for the insertion of a pin 112 to penetrate through the sleeve 11, and a buffer 113 vertically extends from the top surface of the sleeve 11.

Both swing arms 20 are respectively pivoted to both ends of the base 10. Each swing arm 20 includes a pivoting arm 21 and a dancer 22 with one end of the dancer pivoted and secured into the pivoting arm 21. Wherein, One end of the pivoting arm 21 opposite to one end of the dancer is pivoted to the base 10 and multiple through holes 211 in series are disposed on the top surface of the pivoting arm 21 to receive insertion by a pin 212 and to secure the dancer 22. The dancer 22 is provided with a first end and a second end with the first end inserting from a free end of the pivoting arm 21 into the pivoting arm 21, and multiple insertion holes 221 coaxially corresponding to those through holes 211 of the pivoting arm are disposed in series on the top surface of the dancer 22. Accordingly, once the pin 212 penetrates through at the same those through holes 211 of the pivoting arm 21 and those insertion holes 221 of the dancer 22, the dancer 22 is secured in position while allowing adjustment of the total length of the swing arm 20 by changing relative positions of those through holes 211 and those insertion holes 221. A pedal 222 for a user to step on is fixed to the top surface of the second end of the dancer 22 and a roller 223 is disposed to the bottom of the dander 22.

The rail unit 30 includes a shaft 31 with the first end of the shaft 31 inserted into the sleeve 11 of the base 10, and multiple through holes 311 are laterally disposed in series on the shaft 31 that penetrate through the shaft 31. Once multiple (two in the preferred embodiment) pins 112 penetrate through those through holes 111 of the sleeve and those through holes 311 of the shaft 31, the shaft 31 is secured in position by those pins 112, and the total length of the shaft 31 and the sleeve 11 is adjusted by changing the relative positions of those through holes 111 of the sleeve and those through holes 311 of the shaft 31. Both sides of the second end of the shaft 31 are respectively fixed with an arc rail platform 32 having the base 10 as the center for both swing arms to roll thereon with the roller 223.

Referring to FIG. 3, upon working on the curved exerciser, the user has his feet respectively stepping on both pedals 222 of the both swing arms 20. Whereas one end of the swing arm 20 is pivoted to the base 10, the user is permitted to execute reciprocal opening up and closing cycles along the arc orbit to achieve the purpose of staying fit and healthy. When both swing arms 20 move closing to each other to get near the central line defined by the shaft 31, the buffer 111 disposed to the sleeve 11 provides its buffering function to partially absorb the impacts resulted from both swing arms 20. Whereas the base 10, both swing arms 20 and the rail unit 30 are connected to one another, impacts produced among them will be offset due to the inner force. Accordingly, the present invention does secure the curved exercise for its user to enjoy workouts.

The preferred embodiment given above is to describe and not to limit the present invention; therefore, any change in data or replacement of equivalent device shall remain falling within the scope of the present invention.

The present invention by providing an improved construction of a positioning device for the curved exerciser and those who are familiar with the art of the present invention are able to realize that the present invention is capable of arriving at its purposes aforesaid; therefore, this application for a utility patent is duly filed accordingly
